摘要：
Two-stage coal liquefaction is improved by separating a light fraction from the first (dissolving) stage effluent, hydrogenating that fraction and reblending the hydrogenated light fraction with the material passed from the first stage to the second stage reactor operating at higher temperature than the first stage.
